Y' My improved heater requires very few parts, and such parts are of thesimplest -shapefand Y-preferab'ly in the form-ofy castingsfand verylittle fnishwork? is required.

The same construction can be utilized in different capacity heaters bymaking the headers of corresponding length and con- 4neet-ing them withthe necessaryf number/of fpipes.. Theassembly of the parts requires verylittle labor as when the covers are off the pipe connections andbushings arev Very readilyaccessible. 'Y e.
